Hyparrhenia is a genus of grasses.[3][4] Many species are known commonly as thatching grass.[5][6][7][8]

They are mostly native to tropical Africa; some can be found in warmer areas in temperate Eurasia, Australia , and Latin America. These are annual and perennial bunch grasses. The inflorescence branches into twin spikes of paired spikelets.[9][10][11]
